How To Control The Thickness Of A Vacuum Bag

1. vacuum bag thin and thick symmetry is the key to the thickness and symmetry of the composite front film. In other words, its thin quality is the prerequisite for improving its quality.

2. The high barrier of plastic film in vacuum bag is closely related to the thickness of plastic film.

3. The uniformity of the plastic film thickness of vacuum bag endangers the Rashin characteristics of plastic film machinery and equipment. Good thickness uniformity of aluminum foil bag plastic film can obtain good packaging printing accuracy and composite quality.

4. For the same material, the greater the thickness of the vacuum bag film, the higher the start-stop heat seal temperature, and vice versa. That is to say, the vacuum bag film thickness is uniform, can obtain a uniform nail quality, to prevent some heat seal hidden dangers.

At present, the vacuum bag on the market mainly uses four-layer structure design, with good water and oxygen separation function. In addition, for quality qualified vacuum products, in the production process must be in accordance with GB and ASTM standards for testing, and in line with national environmental inspection requirements, if enterprises do not know how to carry out testing can directly to the testing technicians to provide third-party inspection reports. For products that need to be exported, they should also comply with stringent environmental standards for packaging materials in the European Union and North America.
